We hired Wellnuts to rebuild our telematics ingestion layer when our old pipeline started dropping events under peak load. They didn't just patch it — they redesigned the data plane so the load we feared became the load we now operate at comfortably.

Fleet management software
that keeps up with every vehicle.
Telematics, ELD compliance and route optimization backends for fleet operators and telematics providers.
We build and scale telematics and fleet management platforms — ingesting OBD-II and J1939 data from mixed device fleets, keeping ELD logs audit-ready, and re-routing vehicles in real time. 200k+ connected devices in production.

Fleet & mobility software capabilities
Software that runs
your moving fleet.
Six core capabilities for operators with vehicles, drivers and routes that must work at the scale your business has — not the scale your spreadsheet handles.
Telematics & Vehicle Data Ingestion
OBD-II, J1939 and CAN-bus ingestion at fleet scale, plus video telematics from in-cab cameras. Vehicle health, fault codes, fuel use, idle time, harsh-braking events, geofence triggers — turned into real-time signals that operations and finance can actually act on.
ELD & Hours-of-Service Compliance
ELD-compliant logging that survives FMCSA audits, with hours-of-service rule engines for cross-jurisdictional fleets. Built so drivers, dispatchers and compliance officers see the same truth on every screen.
Route Optimization & Dispatch
Constraint-aware routing across vehicle types, driver hours, customer time windows and traffic. Real-time re-dispatch when a stop slips or a vehicle breaks down — not just an overnight batch.
Driver Apps & Mobile Experience
Cross-platform driver applications — turn-by-turn, manifests, proof-of-delivery, vehicle inspection, signature capture. Designed for low-bandwidth, low-signal reality, not flagship phones.
Fuel & Sustainability Analytics
Fuel-card ingestion, MPG normalization across vehicle types, idle-time attribution, EV adoption analytics. The reporting layer that turns a fleet's sustainability KPIs into engineering decisions.
Maintenance & Operator Dashboards
Preventive-maintenance scheduling driven by engine diagnostics and fault codes, plus at-a-glance dashboards for dispatch managers, safety teams and finance. Multi-tenant from the architecture out, so onboarding a new sub-fleet takes hours not weeks.
Featured engagement
An M2M telematics platform for a logistics operator.
A logistics company running a mixed commercial fleet across several regions needed a plug-and-play M2M platform: vehicles had to onboard without engineering touch, and data had to flow in real time without the system losing capacity under load.
We built real-time fleet tracking, in-cab video evidence and driver-behavior monitoring on OWL cam and SmartWitness, ELD modules that record driving and rest hours on every trip, OBD2 engine diagnostics with fault-code collection, and a messaging layer between dispatch and drivers.
Devices & standards
Devices and standards we work with.
Fleet platforms live or die at the device layer. These are the protocols and hardware families we have integrated in production.
OBD-II
Engine diagnostics, fault codes, fuel and odometer data from light and medium-duty vehicles.
J1939
The heavy-duty truck and bus standard — engine, transmission and brake telemetry over the vehicle network.
CAN bus
Raw vehicle-network data when a fleet needs signals that OBD-II and J1939 don't expose.
MQTT
Lightweight device-to-cloud transport for trackers and gateways on unreliable cellular links.
Video telematics
In-cab and road-facing cameras — OWL cam and SmartWitness — for incident evidence and driver coaching.
ELD · HOS
Electronic logging of driving and rest hours with the edit history and audit trail an FMCSA review looks at.
Why operators come to us
What breaks in fleet software — and how we fix it.
The problems fleet operators and telematics providers bring to us, usually after they've already cost money.
Dropped events under peak load
Morning dispatch, end-of-shift uploads, a firmware push to every tracker at once — peaks are when telemetry pipelines start dropping data. We build ingestion on Elixir/OTP, so peak load is routine traffic, not an incident.
A new tracker model takes months to onboard
Every device vendor speaks its own dialect. We normalize protocols behind one ingestion layer, so a new tracker model becomes a parser and a test suite, not a rewrite of the platform.
The ELD audit is next month
Hours-of-service logs that don't reconcile turn an audit into a fire drill. We build ELD logging that keeps drivers, dispatch and compliance on the same record, ready for review at any time.
Dispatch runs on spreadsheets
When routes, drivers and vehicles live in spreadsheets, every late stop is a phone call. We replace them with real-time dispatch that re-routes when a stop slips or a vehicle breaks down.
Telemetry storage grows faster than the fleet
Raw telemetry piles up quickly, and the cloud bill follows. We design retention, downsampling and storage tiers so cost grows with the value of the data, not its volume.
Drivers won't use the app offline
Drivers work where the signal drops. We build offline-first driver apps that keep manifests, inspections and proof-of-delivery working without coverage, and sync when it comes back.
Client voices
Words from operators we've grown with.
The team delivers as if they were our own engineers. The same standups, the same dashboards, the same accountability. After three years it stopped feeling like an outside partnership.
